10 gm equimolar mixture of $KHCO_{3}$ and $K_{2} CO_{3}$ after treatment with KOH is dried & heated. What will be mass (in gm) of $CO_{2} (g)$ obtained after heating ?

[Atomic mass of K = 39]

Answer:

Solution:

$KHCO_{3} + KOH \to K_{2} CO_{3} + H_{2} O$

$K_{2} CO_{3} + KOH \to No Rxn$

$CO_{2}$ is not formed
